Find an angle between \( 0^{\circ} \) and \( 360^{\circ} \) that is coterminous with \( \begin{array}{ll}\text { (a) } 590^{\circ}=\square & \text { (b) }-540^{\circ}=\square\end{array} \)

Given that \( \theta \) is an obtuse angle and \( \operatorname{cosec} \theta=k \), express, in terms of \( k \) (a) \( \cot \theta \)
